Lawn clippings and trimmings gathered by brooms, rakes, or leaf blowers should be disposed of in the green waste container, never in the gutter or storm drain.

Consider implementing Integrated Pest Management (IPM) principles which minimizes the need for pesticides in the first place.  Use pesticides and fertilizers only as directed. Do not over-apply these chemicals and never use pesticides or fertilizers when rain is predicted within 48-hours

Use drip irrigation or hand water with a spray nozzle on the hose to prevent overwatering and water runoff from carrying pollutants into the storm drain

For proper landscape maintenance, make sure to maintain a clean site and prevent debris from entering the street or nearby creeks.  Ensure soil and mulch are applied properly to prevent these from being washed away into the storm system.

Make sure to sweep up dry spills and use cat litter, towels, or similar materials to absorb wet spills. Dispose of all materials directly into the trash

Keep toxic substances and liquid waste off the pavement, ground, or near a storm drain. Even materials that seem harmless such as latex paint or biodegradable cleaners can damage the environment
